From the Document: "The U.S. government has allocated approximately $141 billion for reconstruction in Afghanistan since 2002. We have issued over 400 reports covering U.S. government activities in Afghanistan during this period, about a quarter of which involved U.S.-funded reconstruction efforts. You asked us to report on waste, fraud, and abuse that GAO [Government Accountability Office] uncovered with respect to U.S. reconstruction efforts in Afghanistan. In this report, we summarize the systemic internal control weaknesses that increased the risk of waste, fraud, and abuse related to Afghanistan reconstruction we identified in prior GAO work."
